Need a new 4 channel Amplifier...considering these

Looking for a new amp to power my fronts and mids.

These are the ones I'm looking at:

100 Watts x 4

4 Ch. Power @ 2-ohm (CEA-2006-A):

150 Watts x 4

Mono Power @ 4-ohm(CEA-2006-A):

300 Watts x 2

Adj. HP Q (0.707 to 1.6)

Kicker ZX650.4

RMS Power Rating (@ 14.4V):

• 4 ohms: 120 watts x 4 chan.

• THD + N: 0.05%

• Signal-to-noise ratio: 85dBA (reference to 1 watt)

• Signal-to-noise ratio: 106dBA (reference to rated power)

* CEA-2006A-compliant

Soundstream REF4.760

Channels 4

RMS Power @ 4Ω, 14.4V 4 x 115

RMS Power @ 2Ω, 14.4V 4 x 155

RMS Power @ 4Ω Bridged, 14.4V 2 x 380

RMS Power @ 1Ω, 14.4V -

Total Harmonic Distortion (4Ω power) 0.02%

Frequency Response 15-50kHz

Signal-to-Noise Ratio (4Ω power) 102dB

Damping Factor (100Hz, 4Ω)

Dimensions: 2.25"h x 9.875" 55mm x 250mm 20.25" 514.5mm

Ch. 1&2 HPF/Hawkins/Subsonic (12dB Slope / 0-10dB Hawkins Boost) 15Hz-4kHz

Channels 1&2 LPF* (12dB Slope) -

Channels 3&4 HPF* (12dB Slope) 15Hz-4kHz

Channels 3&4 LPF* (12dB Slope) 50Hz-4kHz

I'm leaning towards the Soundstream because It's a nice amp and I can get a hell of a deal or the Boston because it's 1ohm stereo/2ohm mono stable making it very versatile. I could use it for other applications later if I'm not happy with it in this capacity. However the Kicker is nice as well and has a 2 yr warranty.

Anyone?

Out of those listed, I too would choose the Sound Stream. It's probably the cleanest sounding out of the bunch.

This I have no doubt. The only other one I've heard is the Kicker, and I like that fact they they are often under-rated. But, this Soundstream, for what I can

get it for is a no brainer in terms of SQ for the $. That Boston amp just really intrigued me.

I would pick the BA or SS. Kicker makes good amps though.

I'd do the boston.

Do you guys think the MB Quart Q4.150 is worth a look among these?

The Phoenix Gold is an incredible amp, but severely overpowered for my situation. I know details were not given, so I appreciate the time.

The Critical Mass amp, while exquisite, will undoubtedly be beyond my budget. Again, I didn't state anything about that.

The MB Quarts I am familiar with and am contemplating the Q4.150 and Q4.80. Cadence has yet to fully earn my trust, however I'm testing a 2 channel amp in my wife's car at the moment and and so far have no issues. It's nothing exceptional, but does what it's supposed to do willingly. However, it's not a top of the line series either.

I am pretty sure you would be happy with that SS. And for that supposed killer pricing you would be getting it at, seems like a no brainer to me.

I'm looking into these same amps! which would stay the coolest?? I'm assuming the Kicker would have the most power from my experience with them.

You pretty much can't go wrong with Kicker's amps.

But for SQ AND Power, I was really leaning towards that SS REF4.760. But the amp I got back will do just fine.
